A. BINGHAM, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO BINGHAM & BAILEY.

INKSTAND.

To all whom t may concern Be it known that I, ALBERT BINGHAM, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Inlstands; and I do hereby declare that the same is fully described and represented in the following specification and accompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure l, denotes a front elevation; Fig. 2, a. side view, and Fig. 3, a vertical central and longitudinal section, of one of my improved inlstands.

The nature of my invention consists in applying to, or combining with a gravitatlng or spring cover of the ink port, or pen hole, a bow lever; against which, while the pen is held in the hand of a personyand in the proper manner forbeing written with, and the hand is moved toward the ink port or pen hole for the purpose of inserting the point of the pen into the said port cr hole, the hand shall so be brought in contact with the bow lever as to cause the cover to be raised off the ink port or hole before the pen may reach the same; the cover dropping down and covering the port after removal of the hand from the bow lever.

In the drawings A, is the ink reservoir or vessel not only provided with a port or pen hole B, but a raised chamber or space I), for the reception of a plunger, block or ink elevator E, the latter being elevated out of, or depressed into the liquid of the vessel A, by means of a screw F. The downward movement of the block E, serves to raise the surface of the ink in the vessel A.

The opening or pen port B, is furnished with a cover G, hinged to it on its rear side as seen at a. Above the cover and turning upward on fulcra, at its rear end, is a bent wire or bow lever H, which extends under projections or ears o, Z), projecting from ,the cover in front of the hinge; the position of such bow lever, with respect to the cover, be-

ing such as is exhibited in the drawings.'

By moving the hand against the part of the bow lever, which is in front of and above the cover, the latter may be raised up, and a pen held in the hand may be inserted into the ink port, B. As soon as the pen is withdrawn, and the hand removed from the wire or bow lever, the cover will fall by its gravity and cover the ink port.

By keeping the ink port covered, not only will dirt be excluded from entrance therein, but evaporation of the ink will be essentially prevented.

I claim- Arranging and combining with the hinged cover G, of the pen port B, substantially as described, the bow lever H, whereby the cover may be raised under circumstances and in the manner as specified.

In testimony whereof, I have hereunto set my signature this first day of August A. D. 1853.

ALBERT BINGHAM.
